Trouble with custom swql query in device view

Hello,

I'm attempting run a simple query (below) as a custom resource within a phone device view in vnqm, but getting "Error: A query to the SolarWinds Information Service failed"

Any way I can get some more info on the error to determine if it's a network/firewall/permissions issue as opposed to an issue with the syntax?

I've modified the query several different ways that work in report writer and sql studio, but none of those seem to take in the custom query request.

select top 10

voipccmphones.mac_address,
voipccmphones.name,
voipccmphones.description

from orionnpm.dbo.voipccmphones

Thanks!
